Tackling sample preparation for elemental analysis in the lithium-ion battery industry

This report demonstrates how the use of microwave-assisted closed vessel digestions makes feasible the metal analysis of several components used in the Li-ion battery industry. Moreover, this approach led to shorter digestion cycles, using lower volumes of reagents and higher temperatures without compromising safety aspects.

Sensitive determination of elements in lithium batteries using the Thermo Scientific iCAP PRO XP ICP OES

This report demonstrates a fast analytical method for the determination of major and trace elements in the ternary cathode material of lithium batteries using the Thermo Scientific™ iCAP™ PRO Series ICP-OES.

Low-level consistent analysis of PBDEs in environmental and food matrices using triple quadrupole GC-MS/MS

This report demonstrates that the engineered design and the improved sensitivity of the NeverVent AEI ion source of the TSQ 9610 triple quadrupole mass spectrometer allowed for low instrument detection limits ranging from 5 fg to 122 fg OC.

Ethos UP High Performance Microwave Digestion Systems

The new ETHOS UP^TM is simply the most advanced yet easy to use system for microwave sample preparation we have ever manufactured. It offers a perfect integration between microwave hardware, user interface, digestion sensors and pressure vessels.

Perform like a PRO – Thermo Scientific™ iCAP™ PRO X ICP-OES system delivers Simplicity, Speed and Robustness

This system combines powerful multi-element capability with flexibility, so your lab is ready for any challenge. Experience enhanced sample throughput, matrix tolerance, and flexibility to produce results you can trust.
